About this product

The Sunix DPAS04HP0 DevicePort Advanced is a secure, Ethernet-enabled serial device server featuring 4 x powered RS-232 ports with WiFi support, designed for controlled serial over IP deployments where data protection and flexible port expansion are essential.

Overview Summary

Description

The Sunix DPAS04HP0 DevicePort Advanced is engineered for environments requiring secure and scalable serial over Ethernet connectivity. With four powered RS-232 ports and support for Ethernet and WiFi communication, it enables legacy serial devices to be integrated into modern IP networks without compromising security.

Its daisy chain capability allows expansion up to 255 serial ports, supporting complex installations while maintaining centralized management. The Sunix DPL2000Q chipset ensures stable performance at data rates up to 115 Kbps, while advanced ESD and line protection safeguard connected equipment in electrically noisy environments.

Designed with security in mind, the USB-powered architecture helps prevent online spy recording, and DevicePort Dock Mode restricts Ethernet access to a dedicated PC, making it suitable for sensitive applications where controlled access is required.
